Randomized Controlled Trial
Cardiovascular and lipid-lowering effects of a marine lipoprotein extract in a high-fat diet-induced obesity mouse model.
Obesity is a major health challenge worldwide, with implications for diabetes, hypertension and cardiovascular disease (CVD). Regular consumption of dark-meat fish is linked to a lower incidence of CVD and associated metabolic disorders due to the presence of long-chain omega-3 fatty acid ethyl esters in fish oils. The aim of the present study was to determine whether a marine compound like a sardine lipoprotein extract (RCI-1502), regulates fat accumulation in the heart of a high-fat diet-induced (HFD) mouse model of obesity. ⋯ RCI-1502 significantly reduced triacylglyceride, low-density lipoprotein and total-cholesterol concentrations in serum, but increased HDL-cholesterol levels. Our data show that RCI-1502 is beneficial for reducing obesity associated with a long-term HFD, possibly by exerting a protective effect on lipidic homeostasis, indicated also by histopathological analysis. These results collectively indicate that RCI-1502 acts as a cardiovascular therapeutic nutraceutical agent, which modulates fat-induced inflammation and improves metabolic health.

Objective: Vietnam is endemic with tuberculosis (TB), which is highly prevalent in the community. TB tenosynovitis of the wrist and hand is uncommon. Because of its insidious progression and atypical presentations, it is often difficult to diagnose, leading to treatment delays. ⋯ Ultrasound is a useful tool to support the diagnosis. A histological examination confirms the diagnosis. Most cases respond and have a good outcome after 9-12 months of anti-tuberculosis treatment.

Background: Sideroflexins (SFXNs) are a family of highly conserved mitochondrial transporters which regulate iron homeostasis and mitochondrial respiratory chain. However, the roles and mechanisms of SFXNs in HCC remain unknown. Methods: SFXNs expression and prognostic value in HCC was comprehensively analyzed. ⋯ In vivo, knockdown of SFXN4 inhibited the growth of tumor xenografts in mice. Conclusion: SFXN4 was upregulated in HCC, predicted poor prognosis, and may facilitate HCC development and progression via various mechanisms. For HCC, SFXN4 may provide both prognostic information and therapeutic potential.

Sirtuin6 (SIRT6) has been demonstrated to be involved in a range of physiological processes and diseases, while its role in acute respiratory distress syndrome (ARDS) remains unclear. Therefore, this study focused on the role and underlying mechanism of SIRT6 in ARDS with the aim of identifying potential therapeutic targets. In this study, we found that SIRT6 was significantly decreased in lipopolysaccharide (LPS)-induced A549 cells and a murine model. ⋯ In vivo, the SIRT6-specific inhibitor OSS_128167 also significantly accelerated LPS-induced loss of tight junction proteins, lung inflammation, and apoptosis. Meanwhile, the SIRT6-specific inhibitor OSS_128167 also activated the ERK1/2 pathway and inhibited lung autophagy. These results suggested that SIRT6 could ameliorate the loss of tight junction proteins, inflammation, and apoptosis in LPS-induced ARDS by inhibiting the ERK1/ 2 pathway and enhancing autophagy, indicating that SIRT6 plays a beneficial role in ARDS and might be a potential therapeutic target for ARDS.

Objective: Hyperprolactinemia (HPRL) and polycystic ovary syndrome (PCOS) are common causes of infertility in women of reproductive age. A pituitary adenoma (PA) is the most common type of brain tumor that causes HPRL. In the neurosurgical field, the co-existence of PA and PCOS is not common. ⋯ PCOS patients with a PRL level of ≥ 52.9 ng/mL may need to undergo sella MRI for detecting PAs. To help ensure a favorable clinical course for these patients, systematic diagnosis, treatment, and follow-up plan should be established. Therefore, a multidisciplinary approach involving both neurosurgery and gynecology is essential.
